in Ancient Geography, a people of Gallia Celtica, situated on the Sequana to the south of the Parifil, near the confluence of the Jeana or Yonne with the above mentioned river. Their most considerable exploit was their invasion of Italy, and taking and burning Rome, as related under that article. This was done by a colony of them long before transplanted into Italy, and settled on the Adriatic. Their capital Agendicum in Gaul, was in the lower age called Senones, now Sens. In Italy the Senones extended themselves as far as the river Arès; but were afterwards driven beyond the Rubicon, which became the boundary of Gallia Cisalpina, (Polybius, Strabo).
